Het Fenikshof
While tours of the Grimbergen Abbey brewery aren't possible, you can taste the fruits of its labor at its brasserie in town, which is slightly more upmarket than you'd imagine. A pretty terrace overlooks the abbey, while the food served is unrepentantly Flemish: beery stews, grey-shrimp croquettes, Oostend-style fish stew. Everything on the menu, unsurprisingly, has a suggested beer pairing, as if you needed an excuse to try any of the nine varieties on offer. The quadruple weighs in at a hefty 10% ABV, so it may be a sleepy bus journey back.
